From global to local: testing the potential of cross-scaling in global data sets

The present study investigates the potential of readily available and easily accessible global data sets to understand regional/local level interactions in wetland systems. The biogeographical zones of India were used a base-frame to select three sites. The study well fits the interests of National Wetland Committee of India to investigate and document fundamental information on wetland extent/distribution. The national partnership with SACON represents this interest.

Toward a global inventory of coral reefs (GICOR): Remote sensing, international cooperation and ReefBase

The degradation of coral reefs has become an issue of global concern. Assessment of the status of coral reefs worldwide requires more empirical information on the location and extent of these biologically and economically important resources. In this paper, the authors propose an international program to mobilize technological resources in support of a Global Inventory of Coral Reefs (GICOR).

Recommendation domains for pond aquaculture

This publication introduces the methods and results of a research project that has developed a set of decision-support tools to identify places and sets of conditions for which a particular target aquaculture technology is considered feasible and therefore good to promote. The tools also identify the nature of constraints to aquaculture development and thereby shed light on appropriate interventions to realize the potential of the target areas.

A low-level geographic information system for coastal zone management with applications to Brunei Darussalam: Part III:: simulation and tracking oil spills.

B:RUN is a low-level GIS software designed to help formulate options for the management of the coastal zone of Brunei Darussalam. This contribution presents the oil spill simulation module of B:RUN. This simple module, based largely on wind and sea surface current vector parameters, may be helpful in formulating relevant oil spill contingency plans. It can be easily adapted to other areas, as can the B:RUN software itself.

Using ReefBase to create customized maps

One of the most popular sections of the ReefBase website is the online GIS that enables users to create an almost unlimited range of maps showing a wide variety of features. A new version of the GIS, offering an even larger array of facilities and data layers, is online as of early September. In this article, we will provide an introduction to the ReefBase GIS and also highlight some of the powerful but lesser used features of the system.

CBD 2010 target: a case study of Kolleru Wetland (Ramsar Site), India using remote sensing and GIS

Regular monitoring of wetlands is an essential element of management for 'wise use'. Indeed, the Ramsar convention requires routine monitoring in order to detect changes in the ecological character at listed sites. However, there are few examples of monitoring of tropical wetlands on a sustained basis in the world. In the present study, we quantified land use/land cover changes in the lone Ramsar site, the Kolleru Wildlife Sanctuary of Andhra Pradesh, India between 1977 and 2007 using remote sensing and GIS techniques.

Spatial dynamics versus social dynamics: understanding trade offs in ecological and socio-economic systems

This paper is based on a first phase of a study in the Muthurajawela-Negombo wetland complex and aims to assess the overall spatial linkages between ecological and socioeonomic aspects of the wetland system using a geospatial model; incorporating biophysical and socioeconomic parameters for analysing and modelling the changes in the coastal wetland-agriculture-aquaculture complex.

The use of remote sensing and geographic information systems in coastal zone management.

This paper outlines the opportunities and constraints in the use of remote sensing technology and geographic information systems (GIS) for coastal zone management (CZM). Extensive applications of remote sensing under ASEAN/US CRMP were hindered by cost, lack of familiarity with the methodologies, lack of technical expertise and inaccessibility of remotely sensed data. The use of GIS in CRMP was limited to the Malaysian project. Although many of the real-world complexities of the coastal zone cannot be adequately represented in current GIS, it still serves as a useful tool for CZM.

Remote sensing application to study the aquaculture dynamics in Kolleru Lake, India

Kolleru lake, India’s largest fresh water lake, and lone Ramsar site in Andhra Pradesh state have undergone tremendous changes due to development of aquaculture. Large-scale aquaculture practices, increased industrial activity, increased number of human settlements, etc. have exploited the lake’s resources which created an extensive ecological imbalance, hence instabilising the sustainability process. The present study highlights the assessment of aquaculture in Kolleru lake using multi-temporal satellite datasets.

Assessing forest canopy closure in a geospatial medium to address management concerns for tropical islands: Southeast Asia

The present study outlines an approach to classify forest density and to estimate canopy closure of the forest of the Andaman and Nicobar archipelago. The vector layers generated for the study area using satellite data was validated with the field knowledge of the surveyed ground control points. The framework developed would serve as a significant measure to forest health and evaluate management concerns whilst addressing issues such as gap identification, conservation prioritisation and disaster management -- principally to the post-tsunami assessment and analysis.
